FBANKLIN RANSOM, OF BUFFALO, NEW YORK.

CHURN.

T0 all whom z't mag concern:

Be in known that l, FRANKLIN RANSOM, of the eity 0f Buffalo, county 0f Erie, and State of New York, have invented new and useful Improvements in Ohurns; and I d0 hereby deelare that the following is a full, clear, and exact dcscription thereof, reference being had 130 the accompanying drawings, making a partof this specifieation, in whieh Figure I is a vertieal seetion, und Fig. II is a plan view.

Letters 0f ]ike name and kind refer t0 like parts in eaeh of the figures.

The nature of this invention relates, firsf, to the agitation 0f the eream or milk by centrifugal furee predueed by a propeller 0f a mueh less diameter than the diameter 0f the churn-tubsayone-third 01 one-half thediameter 0f the churn-tub-in combination with a perforated. disk and vacuum-forming drum, (either 01 both 0f them,) whieh for1n extra rubbing and frictional surfaces aguinst whieh the crealm 01 milk must impinge or rub in its movements; second, t0 aventilating-cyliuder plaeed 011 the upper side und near the center of the disk a-nd around the propellershaft; third, to placing breakwings upon either the upper 01 lower side of the disk in Order to prevent the cream from obtaining a free ro tary motion, lud to direct it to the eenter ag;mn.

A represents the churn tub, which may be made of any required size 01 form.

B is the propeller, and B propeller-shaft, and U, C, O and D appropriate and (30111111011 gearing, shaft, and crauk,for giving motion to the propeller. The ropeller deseribes u circle of mach less diameter, 00111 paratively, zus it revolves than the diameter of the ehurntub, so as 130 throw ehe cream centrifugally With great veloeity through the perforations in the drum and disk.

E is a n1ovable 0r hollow drum, open ab bot:h ends, and placed eentrally 0n the bottom of the ehurn-tub and around the propeller. II; is a little larger in diameter than the propeller and 0f less diameter than the churntub. II: has numerous holes made through its body, a-s shown ab e. (Ehe action 0f the prope1ler forces the crezun outwardly through these holes und upwardly through the perforations in the d'isk.

*F is a perforated disk 0f equal diameter t0 the inside diameter of the cl1uru-tub. It is placed inside 0f the churn-tub and in contact with the drum E. Oatch-wings or breakers f in Fig. II nmy be conneeted so the bottom 0f the disk, radiating from t]ie drum t0 the ehurn-tub, and dividing the annular space between said drum and ehurn-tub, which will operate t0 break and retard a rotary motion of the cream. There are also wings projecting upwardly from the upper side of the disk, as shown at f which serve as breaks, so 0bstruct a free rotary motion 0f the cream 01 milk on the upper side of the disk, and give it direction back to the center. f 3 are holes through the disk.

G represents a hollow c ylindex .open at both ends, and perforated ab the sides, .as shown ab g. 'lhis cylinder is sei; upon the upper side 0f the disk and surrounds the propeller-shaff, 218 shown in the drawings. This device need not be used when there is but a small quantity of eream in the ehurn; hat; when the1e is a large quantity, sufficient t0 submerge the disk F, it; serves the purpose of drawiug air into the eream, and produces a greater vacuum-space around. the propeller, which eauses currents 0f cream to rush in through the holes, and thence downwardly through the central holes in the disk to the propeller, t0 be driven outwardly again by the propeller through the openings in the lower drurn and upwardly through the outer holes in the disk. 'lh'us, by this movement from the center outwardly, und fr0m the periphery inwardly, to the center again, the eream is kept eonstantly agitated, penetrated with air, und foreed with great veloeity against the frictional perforated surfaces 0f the drum, cylinder, and. disk, and tl1e churning is aeeomplished with a slight; comparative expenditure 0f power, and quiekly and suecessfully.

WVhat I elaim as my invention, and desire 130 secure .by Letters Patent, is

1. 'lhe application am]. use of rotating blades or propeller B, 0f mueh less diameter than the diameter 0f the churn-tub, in combination with the perforated disk F und hol- 3. The break-wings f f plaeed either 10W cylinder E, (either 01" both of them,) f01 upon the upper o1 lower side 0f the disk, f0r

ehe purposes and substantially as herein dethe purposes and substantially as sei: forth.
